'Inthe embodiment'illustrated, there is preterably provideda base it having secured thereon a ticker Zprei'erably"oi=thehigh speed type which has aftape discharge outlet 3 from which the whom-there down under the finger I formed at :i the end oi, the lever 3 operatively connected to the automatically operated switch disposed inthe housing '1 for controlling thecurrent oi the electric motor 8 in the manner coj these machines. Fromthe fin ger'l the t now well known with ape passes over the on the -bracket'31 and then to and curved guide! whichis I the housing extension In. By means oi." this guide 9, the tape'is guided to and between the projections ii and l2 at the entrance end oi the a light aperture for the condenser 13. At this en'- weight is; is provided v spaced irom one another to clearthe two rows 01' printed matter as a rule formed on the tapeT by the high speed ticker, such for instance as the row defined by the'word Tape and the other defined by the number "100". z

The light aperture for the condenser I3 designated 23 isiormed by an wall 24'of the extension I0 and the upper end of the light aperture 23 is defined by thefiange 25 extending down from the covergi1. From the aperture 23, the tape passes to thetape guides 26 formed at the end of the light aperture'23, which guide consists essentially of at its upper end and projections its lower end and guide rollers I guide roller 29 being disposed at the entrance end of the guideadjacent to the light apertur'e 23 and the guide roller 30 being disposed at the discharge end or the guide.

From the roller 30, see Fig.' 1; the tape passes to and across the light aperture 3i formed in the.

wall32 ofthe extension Ill to'cooperate with the condenser". I r v t t From the light'aperture 3|, the tape passes to and over'the roller 34 at the end of thelight aperture 3| secured in the bracket 35 from which the tape passes to and beyond the idler 36 formed over the drive sheave 38 in engagement with which the tape is maintained by the friction roller 33 which is I mounted on the lever 40 pivotally mounted at 4| on the bracket 31 and having an abutment 42 WhlCh,iS connected by the spring. 43 with the frame 31, resiliently to maintain the friction roller 39 in engagement with the tape T.. t'

From the pulling sheave 38, the tape passes to and around the idler 44 and then to the rewind reel 4i m o'unted on the arm 46 of the bracket 31. The motor I is drivingly connected to the pulling sheave 33 and rewind reely45, the shaft of the motor 8 being provided with a pulley 41 which is connected by the belt 48 to the pulley on the shaft, which has formed thereon a worm Si in engagement with the worm wheel 52 mounted on the shaft 33 of the pulling sheave 38.

The shaft 53 has also formed thereon a pulley 54 which is connected by'the spring belt 55 with he pulley 58 on the shaft 51 of the rewind reel secured to the side of plate l4, there is the pin i8 having adjustably'mounted thereon a counter-i The tape engagingend of the plate withfthree projections 20; 2i and 22:

. for the light rays issuing from the lamp '60 and 45. The bracket 31 preferably as shown is secured to and mounted on a vertical wall of one of the lamp housingextensions58. 3 i l The lamp housing extension 58'is disposed at right angles to the lamp housing extension 59.

The extensions 58 and 59 are substantially rec' tangular and have their adjacent corners preferably integral with one another as shown in Fig.

1. The triangular space formed between the front endsof the extensions 58 and 59 is preferably provided with a triangular housing 68' hav-- ing a vertical wall member I58 extending downwardly therefrom. The'extension' l0 issubstantially rectangular but has two of its opposed corners cut off, the one to form a face flush with the wall 68%, see Fig. 4, and the other to form the inclined face in'allneme'nt with the guide 26.

These extensions 58 59 and "land housin glit are connected to one another to form a oomposite housingfor the projecting machine head. I

"The wall .24 in which'thelight apert e 23 is formed is v dispose'din' line with the light ,raysissuing from the lamp 60 formed in the extension 58, and the light aperture 3| islidisposed'lnlpositiontoreceive the light rays issuing fromthe lamp 6L, The arrangement'of lightapertures .23, Hand lampsilif, 6| respectively, is such thatthe light rays from the lamps 50. .6! will cross at substantially right angles to one another and the light apertures 23'a'nd 3| 'as' lllustratedin'Fig'. 1. are disposed in planes that are substantially at right angles to oneanother.

The extensions 58 and59 are substantially identical with one another, eachhaving a reflector 62 formed in the rear end lthereof,.a light and heat" cut-off shield 63. having an aperture 64 therein disposed between the reflector and the. lamp," a. pair of condensers 65.and 66 mounted in.

the condenser 33'for'th'e light rays issuing from thelampGL. r

. With the arrangement aforesaid the light rays. from two different lamps 60 andi l that is lamps having different light intensities, may be directed at right angl es to one anotherthrough asingle tape disposed ina vertical plane and passing light apertures that are dlsposedat substantiallyright angles to one another, to wit, the light apertures 23"and3L The extension l0, seepartlcularly Fig. 4, is

much shallower than the lamp housings 58 and 59. This shallow construction serves apartioular function in the present instance In they present instance, it will be seen, sce Fig. 4, that, the wall 58* extends vertically downward from a point just below the level of-the upper end. of the housings. 58 and 59 and from one free corner to the other of such lamp'housin'gs 58 and 59. This wall extends down to alevel'more than one-third of the distance from'the upper end of thehousing '58 to its lower end.

At this lower end, the wall aflange 69 'to which is hinged'the cover 11 by means 'of the hinges I0 and'll. Adjacent to the guide 26', there is formed the bracket 12 on which is mounted the pin' 13. In the cover I1, there is formed an opening vto register with the; pin 13 and permit the head .Hl ofthe pin" to extend'up and above the upper faced the cover l|. On the cover ll, there is pivotally mounted the hook 15 est is'provided with which is adapted to engage the head "of the pin 13 and anchor the cover in closed position.

. The cover is provided with twoshortifianges,

to wit, the flanges 25 and 16 to form and define the upper edges of the light apertures 23 and3l "respectively.

,. The condensers l3 and 33 are cut to form a face at'right angles to their plane faces above or beyond their efiective light condensing area. These upper plane faces 11 of the condensers l3 and 33 are adapted to cooperate with the cover I! to determinetheir position. at the light apertures'23 a d-1 I To facilitate guiding the condenser 13 in a vertical direction, there are provided lateral guides 18 and to provide vertical guides for: the condenser 33, there are provided lateralguides 19.1 For re-r siliently maintaining the condensers l3 and 33 upwardly in engagement with the cover [1, there are provided the spring arms 80, engaging the condenser 13 belowlits thickest areato cooperate withtheconvex face ofthe condenser l3 to urge it upwardly against the cover I1, and outwardly.

against the wall 24 and for the condenser 33,,there are-provided the spring, arms 8|, 8|;forxsimi1arly engag'ingthe convex face of the condenser 33 belowiits thickest-area to urge it upwardly against the'cover I1, and outwardly against the wall 32.

In turn when the'cover I1 .is raised, the condensers I3 and 33 may project above their normal level but will be pressed back into their proper position immediately that the cover a, .I 1; is closed and secured by the hook I5.

Inthe present embodiment, it will be seen the condenser I3 is much thinnerthan the condenser 33 and is designed for a long focal. axis.

to cooperate with the lenses formed in the housing 82 mounted on thebracket 83andthatj the condenser 33 cooperateswith the optical lenses.

formed in the housing 84 mounted on the bracket 85 and is designed for a shorter focal axis. x From the foregoing, it willthus appear that irrespective of the variations 'between the focal axes of the condensersusedat the light apertures 23, 3!, the springarms-amtfl and 8|, 8| and cover- 11 will be effective automatically to position any and all of them. a

Itwould also appear from the foregoing that when it is desired, according to the installation,

to have a'condenser of a different focal axis than that originally supplied, it will only be necessary to remove the condenser supplied and replace it with the desired one. I

It is obvious that various changes and modifications may be made to the details of construction withoutdeparting from the general spirit of the invention as set forth in the appended claims.
